Abstract
In this paper, DC timing system controlled by puter had been researched deeply. Beginning with the theory of the DC timing system, the math model of the double closed loops DC timing system had been build up, the controller parameter had been adjusted after the system had been simulated with MATLAB, Based on the result of the simulation, digital signal processor (DSP) is taken as the controller, the design of the double closed loops timing system of the DC motor has been realized through the design of the system’s hardware and software. The result shows that this timing system has strong robust.
Keywords: puter control, double closed loops, DC timing, DSP
